PDGFRA

This gene encodes a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. Studies suggest that this gene plays a role in organ development, wound healing, and tumor progression. Mutations in this gene have been associated with idiopathic hypereosinophilic syndrome, somatic and familial gastrointestinal stromal tumors, and a variety of other cancers.

Predicted location

Intracellular, Membrane (different isoforms)

Single cell type specificity

Group enriched (Oligodendrocyte precursor cells, Leydig cells, Endometrial stromal cells, Peritubular cells, Fibroblasts)

Immune cell specificity

Not detected in immune cells

Cell line specificity

Cell line enhanced (ASC diff, ASC TERT1, BJ hTERT+, fHDF/TERT166, HHSteC, HSkMC)

Interaction

Interacts with homodimeric PDGFA, PDGFB and PDGFC, and with heterodimers formed by PDGFA and PDGFB. Monomer in the absence of bound ligand. Interaction with dimeric PDGFA, PDGFB and/or PDGFC leads to receptor dimerization, where both PDGFRA homodimers and heterodimers with PDGFRB are observed. Interacts (tyrosine phosphorylated) with SHB (via SH2 domain) (By similarity). Interacts (tyrosine phosphorylated) with SHF (via SH2 domain). Interacts (tyrosine phosphorylated) with SRC (via SH2 domain). Interacts (tyrosine phosphorylated) with PIK3R1. Interacts (tyrosine phosphorylated) with PLCG1 (via SH2 domain). Interacts (tyrosine phosphorylated) with CRK, GRB2 and GRB7. (Microbial infection) Interacts with human cytomegalovirus/HHV-5 envelope glycoprotein B/gB. Interacts also with the trimeric complex gH-gL-gO.

Molecular function

Developmental protein, Kinase, Receptor, Transferase, Tyrosine-protein kinase
